From 295c1b9852d000580786375304a9800bd9634d15 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Fri, 10 Jul 2020 06:36:16 -0400 Subject: [PATCH] vhost/scsi: fix up req type endian-ness vhost/scsi doesn't handle type conversion correctly for request type when using virtio 1.0 and up for BE, or cross-endian platforms. Fix it up using vhost_32_to_cpu. Cc: stable@vger.kernel.org Signed-off-by: Michael S.
